Tuberculosis (TB) is a serious and important public health issue to be addressed in India. Timely diagnosis of the drug resistance tuberculosis essential ensure initiate appropriate therapy. The detection resistant Mycobacterium (MTB) cases smear-negative clinical diagnosed pulmonary TB. A prospective case-control study was conducted on 473 samples received at tertiary care center from January ...
A quantitative, fluorescence-based PCR assay (TaqMan-based system) was developed for detection of human herpesvirus 8 (HHV-8) DNA in clinical specimens. Primers and probes chosen from each of five 10-kb segments from the unique region of the HHV-8 genome were evaluated for sensitivity with dilution series of DNA extracted from a cell line (BCBL-1) that harbors HHV-8 DNA. Although several of the...
Probes for use in time-resolved fluorescence competitive binding assays at melanocortin receptors based on the parental ligands MSH(4), MSH(7), and NDP-α-MSH were prepared by solid phase synthesis methods, purified, and characterized. The saturation binding of these probes was studied using HEK-293 cells engineered to overexpress the human melanocortin 4 receptor (hMC4R) as well as the human ch...
Researchers often use melt curve analysis to assess whether their intercalating dye PCR/qPCR assays have produced single, specific products. Specificity of amplification is considered to be a greater concern with intercalating dye assays than with probe-based assays because intercalating dyes bind to any doublestranded DNA product and are not sequence specific. With probe based assays, amplicon...
There is a clear need for an instrument-free molecular diagnostic system for detecting human immunodeficiency virus type 1 (HIV-1) RNA or DNA that can be used in developing countries. Such a test could be used for early diagnosis of HIV-1 infection during infancy and could serve as a surrogate end point for vaccine trials. We developed the IsoAmp HIV-1 assay (BioHelix Corporation), which target...
